PUMP-BORING NIACHENE.

SPECIFICATION forming part of Letters Patent No. 356,846, dated February l, 1887.

(No model.)

To all whom may concern:

Be it known that I, NICKOLAs OLEY, a citizen of the United States, residing at indianapolis, in the county of Marion and State of indiana, have invente-d eert-ein new und useful Improvements in Pump-Boring Machines, of which the following is ai specification.

My invention relates to machines such as are used to bore ont timbers for pump-stocks; sud it consists in the features of construction hereinafter described and claimed.

Figure l is e side view of my improved pump-boring nischineg Fig. 2, e top view of the saine; Fig. 3, e vertical cross-section on line x x on Figs. l and 2; Fig. 4, a vertical cross-section on line e z on Figs. l and 2; Fig. 5, e section through a pump-stock when bored out by my machine.

Similar letters refer to similar ports throughout the several views.

A is the freine-Work which supports the pump-augerB, and upon which slides the cerriage or frame C, that supports and holds the timber or pump-stock D.

The auger B is Constructed in the usual inanner, having a hollow barrel, b, provided with a cutter-head, b', operated byu pulleyand belt, in, and a spirnl ohip-removing rod,'g, inside of the barrel b, operated by another pulley and belt, n.

The timber D is held in position on the oarringe C by the supports I J, theorie of which, I, toward the auger b', forms n universal clamp having tivo separate jaws, ii, sliding laterally in a groove on the frame() and beingoperated by e clamp-screw with e wheel at one end, a fixed center between the jews, and screwtlireads out in diverging directions from the lined center and passing through the jaws i' i, so that turning the wheel in one direction opens the slamp, While turning it in the other shuts the same.

The frame C is moved up to the auger B, l

feeding the timber to the saine, by un endless screw, G, that is secured to the frame A and operated by a pulley and belt, o, the seid screw gearing with a Worm-Wheel firmly attached to the sliding frame G or operating in e screwthreaded shoulder on the frame G.

The machine described so for is old. My improvements consist in the following. instead of supporting the fore end of the anger-barrel on s iixed boxing extending up from the sliding fraineC, l use a universal boxing, F--that is, one which can be disengaged from the berrel, so that it will clear the reniner H when the frame C moves up to the same. This reamer H is constructed in the following manner: A metall sleeve, Iz', is secured to the barrel Z) by moans of sot-screws, bolts if, or the like, at u distance from the cutter-heed o equal to the desired length ol' the lower narrower tubing of the pump-stock. To the sleeve Zz. are secured one or more roaming bits, knives, or cutters 7L.

The device opere-ics es follows: After the timber has been put in position on the supports I J, andthe machine hos been setin motion, the timber being fed up tothe enger bis bored out thegdiameter ofthe auger-bit until the reemer H is renohed. From thence the timberis renined out the diameter of said reainer lvl. Thus the entire pump-stock, with its smalldiameter lower tubing and its large diameter upper steek, is bored out and finished Without being .removed from its supports and without stopping the machine and changing the auger-bits.

To make the boring of the pump-stool; as aforesaid possible, the boxing E, which supports the cutter-head b ol the anger-borrel, must be constructed in sueh a manner that it can be disengaged from the said barrel before the reamer H is reached, or, in other Words, the boxing must open and poss clear of the reamer to the rear end of the` enger-barrel. This is accomplished by making the boxing a universel boxing, consisting ol' tivo sidewiseopening bracket-eff, operated by e iixed endless seremthreuded in opposite directions from a. iixed point in the center between the two brackets f j' in the suine man ner as the universel Clamp l, described hereinbei'oreyor the bracketsff may be hinged or pivoted to the sliding frame O in sueh o manner that they can be unfolded or opened when passing the remuer H.

Having thus described my improvements, what I claim as new, and desire to secure by Letters Patent, is

The combination, with :L supporting-frame, l In testimony whereof I have signed my name of a sliding timber-supportingfmmoprovded to this specification in the presence of two sub- Io With a clamp for the smak, an auger, B, pro- Soribing wsftuesses.` vided with 2L cutter-head, b', the expansbe T K 5 boxing F, mounted on the carriage C, a sleeve, A ICKOLAS OLEY' h, secured to the tube b of the auger, and cutters Wtuesses: h', secured to said sleeve, substantially as seb CHARLES N.
